One of the objects of the invention is to provide means operative to controlthe flow of a fluid in a conduit as: a function of a.

fburetor. When cooling fluid from the motor,

lubricating oil, or exhaust gases are circulat- Yedtherethrough, the carburetor will be supplied with extra air as a functionof temperais to i provide a carburetor air is introduced in quantities which are a yffunction of the temperature offthe motor water-jacket, the exhaust gases, the lubrii .cating oil the motor, as desired.

, Referring to the drawing, there is shown a carburetor assembly composed of a nozzle e of conventional design supplied with fuel from a constant level chamber,amixing chamber 7 fitted with a throttle valve,a supplementary air inlet conduit g, a valve hcontrolling the inlet end of conduit and ,fitted with a stem 2' carrying a cross-piece or piston j,a springh opposing displacement of valve k,-a spider k serving as abutment 0rysp inga cylinder k of somewhat larger section than element y and containing a substance whose viscosity varies considerably as a function of the temperature (grease, heavy oil, Vaseline or mixtures jacket (2) from the oil circulating system or (3) from the motor exhaust;
